Combustion Noise
November, 2008 Anna Schwarz, Johannes Janicka In the last thirty years noise emission has developed into a topic of increasing importance to society and economy. In ?elds such as air, road and rail traf?c, the control of noise emissions and development of associated noise-reduction techno- gies is a central requirement for social acceptance and economical competitiveness. The noise emission of combustion systems is a major part of the task of noise - duction. The following aspects motivate research: • Modern combustion chambers in technical combustion systems with low pol- tion exhausts are 5 - 8 dB louder compared to their predecessors. In the ope- tional state the noise pressure levels a...
Aeroacoustic Measurements
The book describes recent developments in aeroacoustic measurements in wind tunnels and the interpretation of the resulting data. The reader will find the latest measurement techniques described along with examples of the results.
Shock Wave-Boundary-Layer Interactions
Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.
Computational Aeroacoustics
Computational aeroacoustics (CAA) is a relatively new research area. CAA algorithms have developed rapidly and the methods have been applied in many areas of aeroacoustics. The objective of CAA is not simply to develop computational methods but also to use these methods to solve practical aeroacoustics problems and to perform numerical simulation of aeroacoustic phenomena. By analysing the simulation data, an investigator can determine noise generation mechanisms and sound propagation processes. This is both a textbook for graduate students and a reference for researchers in CAA and as such is self-contained. No prior knowledge of numerical methods for solving partial differential equations (PDEs) is needed, however, a general understanding of partial differential equations and basic numerical analysis is assumed. Exercises are included and are designed to be an integral part of the chapter content. In addition, sample computer programs are included to illustrate the implementation of the numerical algorithms.
John Dee's Five Books of Mystery
Discovered in a hidden compartment of an old chest long after his death, the secret writings of John Dee, one of the leading scientists and occultists of Elizabethan England, record in minute detail his research into the occult. Dee concealed his treatises on the nature of humankind's contact with angelic realms and languages throughout his life, and they were nearly lost forever. In his brief biography of John Dee, Joseph Peterson calls him a "true Renaissance man"? detailing his work in astronomy, mathematics, navigation, the arts, astrology, and the occult sciences. He was even thought to be the model for Shakespeare's Prospero. All this was preparation for Dee's main achievement: five bo...
The Romanian Revolution of December 1989
The Romanian Revolution of 1989 was the most spectacularly violent and remains today the most controversial of all the East European upheavals of that year. Despite (or perhaps because of) the media attention the revolution received, it remains shrouded in mystery. How did the seemingly impregnable Ceausescu regime come to be toppled so swiftly and how did Ion Iliescu and the National Salvation Front come to power? Was it by coup d'état? Who were the mysterious "terrorists" who wreaked such havoc on the streets of Bucharest and the other major cities of Romania? Were they members of the notorious securitate? What was the role of the Soviet Union?Blending narrative with analysis, Peter Siani...
Feral
As an investigative journalist, Monbiot found a mission in his ecological boredom, that of learning what it might take to impose a greater state of harmony between himself and nature. He was not one to romanticize undisturbed, primal landscapes, but rather in his attempts to satisfy his cravings for a richer, more authentic life, he came stumbled into the world of restoration and rewilding. When these concepts were first introduced in 2011, very recently, they focused on releasing captive animals into the wild. Soon the definition expanded to describe the reintroduction of animal and plant species to habitats from which they had been excised. Some people began using it to mean the rehabilita...
